No, you cannot bring a foldable wagon or any form of "stroller wagon" to Disneyland. Since May 1, 2019, Disney has strictly enforced a policy that prohibits all wagons and stroller wagons from entering their theme parks. This includes popular models like the Keenz, WonderFold, or Veer, even if they are pushed like a traditional stroller. The rule was implemented to improve guest flow and reduce congestion in high-traffic areas, as wagons take up significantly more space and are harder to maneuver than standard strollers. The only exception to this rule is for guests who have a documented medical necessity that specifically requires a wagon; in such cases, you must visit Guest Relations to have the wagon tagged as a "stroller as wheelchair" or a mobility device. For all other families, any stroller used must be no larger than 31 inches (79 cm) wide and 52 inches (132 cm) long. If you arrive at the security checkpoint with a prohibited wagon, you will be asked to return it to your vehicle or store it in a locker (if it fits) before entering the park.
